Guardian Audio B8MP3 is an 8-channel powered mixer with a USB-MP3 player. It features two XLR low impedance balanced microphone inputs with phantom power for condenser microphones, and two 1/4" line high impedance inputs for high impedance microphones or line level devices. Each channel has a 3-band EQ, reverb control, and channel volume control. The mixer also has a master volume control, CD/tape volume control, and a graphic equalizer. The USB-MP3 player has play/pause, skip track, and stop buttons, as well as a volume control and LCD display.

8 TCC Channel Powered Mixer
With USB-MP3 Player
We use True Channel Count (TCC) on all Guardian Audio®
mixers. A mic channel consists of a minimum of an XLR in-
put, EQ and level controls. A stereo channel consists of a
minimum of a pair of input jacks, EQ and level controls.

FRONT PANEL FEATURES
1) Channel volume control. This control determines how
much signal is sent to the main bus.
2) XLR low impedance balanced microphone input. Phan‐
tom power for condenser microphones. Input imped‐
ance is 10k ohms. The XLR connector is wired PIN 1 =
shield, PIN 2 = hot, PIN 3 = neutral.
3) EQ controls. These adjust the overall tone of the chan‐
nel. They cut or boost high and low frequencies ±15 dB.
4) 1/4” line high impedance input. This input can be used
for a high impedance microphone or line level device
such as keyboards, guitars and CD players. The input im‐
pedance is 10k ohms. Both high and low impedance
jacks can be used simultaneously.
5) Reverb control determines the amount of reverb effect
is sent to the main bus for each channel.
6) Play / Pause buon for the MP3 player.
7) LCD Display shows songs, elapsed me and total me.
8) Track repeat control for the MP3 player.
9) Graphic Equalizer controls ±12dB of boost or cut at
60Hz, 250Hz, 800Hz, 2kHz and 8kHz.
10) Skip to the next track on the MP3 player.
11) Phantom Power turns the 15v phantom power on or off.
12) Blue LED power indicator.
13) LED level display.
14) Master Volume controls the overall volume of the mixer.
15) CD/Tape volume control.
16) USB jack for flash drive.

17) Stop buon for the MP3 player.
18) Effects Controller adjusts the amount and delay me of
the reverb effects.
19) Skip to the previous track on the MP3 player.
20) Volume for the MP3 player.
REAR PANEL FEATURES
21) Tape Input RCA jacks are for tape/CD or other line level
signal. This is 10k ohm @ ‐10dBv.
22) Tape Rec RCA jacks are for sending signal to a recorder.
These are pre‐master and do not have reverb or the Tape
Input signal.
23) Effects Loop Send 1/4” jack for adding external effects,
recording out or adding an addional power amp. This line
level signal is a mirror of the main output.
24) Effects Loop Return 1/4” jack for adding external effects.
This is 10k ohm @ ‐10dBv.
25) Speaker output 1/4” jacks. The minimum impedance for
this amplifier is 4 ohms. A total of one 4 ohm or two 8 ohm
speakers may be connected. Do not operate below 4 ohms.
26) Voltage select switch.
27) IEC connector for 115 volts 60 cycle grounded AC cur‐
rent. Never operate without the ground pin.
28) Power Switch turns the mixer on and off. A front panel
LED lit indicates that the power is on.
